IMPROVEMENT IN F EE D-COOKERS.

Specification forming part of Letters Patent No. 177,284, dated May 9,1876; application filed March 27, 1876.

To all whom it may cancel-m.

Be it known that we, ANDROSS Romans and CHRISTOPHER WINTER s,'ofFreeport, in the county of Stephenson, and in the State of Illinois,have invented certain new and useful Improvements in Feed-Cookers; anddo here by declare that the following is a full, clear, and exactdescription thereof, reference being had to the accompanying drawings,and to the letters of reference marked thereon, making a part of thisspecification.

The nature of our invention consists in the construction and arrangementof a feedcooker, as will be hereinafter more fully set forth. v

In the annexed drawing, Figure l is a -ver.- tical section of ourfeed-cooker. Fig. 2 is a section through the upper partot' thedraftpipe.

A represents the shell of acooker', made of any suitable dimensions, andprovided with a grate, 13, elevated above its bottom. C is thesmoke-pipe, and D is the draft-pipe. The upper part of the draft-pipe Dextends horizontally through the side of the smoke-pipe c, and has adamper, a, as shown. Within the smoke-pipe c the draft-pipe turnsdownward, and extends through and below the center of the grate B, asshown, thus forming a center draft, having the fire all around thedraft-pipe, thereby heating the air as itpasses through more effectuallythan either the outside or inside draft when it is attached to the shellof the cooker.

Another advantage of this arrangement of the draft-pipe is, thatthe'tire is thereby caused to strike the whole of the inside of theshell, thereby causing the Water to come to a boiling heat evenly allaround the cooker, which is not the case where the draft is attached tothe side of the cooker.

The draft- 'npe, running through and below the grate, distributes theair more efi'ectually through the fire as it passes up into the cooker.

We are fully aware that agricultural boilers having an air-supplyingpipe or flue extending down to one side of the grateare not new but insuch inventions as known to us the airsupply pipe is not extended to thecenter of the grate; hence the air is not equally distributed under thegrate.

Having thus fully described our invention, what we claim as new, anddesire to'secure by Letters Patent, is a The combination of the cookerA, having grate B, and the air-supplying pipe D, passing 'down throughthe center of the cooker, and

through and below the center of the grate,

substantially as and for the purposes herein set forth.

In testimony that we claim the foregoing we have hereunto set our hands.
